simple Postfix question

hi all,

My SMTP is not working to email other addressed apart from local ones.

So how do i tell the server to use "smtp.ihug.co.nz" to send email?

This is because the webmail feature is not sending to email that are not my own domain.

i.e [email protected] TO [email protected] works

[email protected] TO [email protected] DOES NOT work

 

Are there any errors in your mail log?

 

um i am not sure how to check the postfix error log but in webmin, i lookin the mail que and here are the messages i try to send to the outsite world.

it says:


Mail ID Sent From To Size Status
2B65310847 Sun Sep 21 22:03:37 [email protected] [email protected] 897 bytes Host or domain name not found. Name service error for name=ihug.co.nz type=MX: Host not found, try again
4F93F108EC Wed Sep 17 17:20:09 [email protected] [email protected] 3.45 kB Host or domain name not found. Name service error for name=ihug.co.nz type=MX: Host not found, try again

Hope that helps show the problem

 

What's in /etc/resolv.conf?

 

all it says is :

Code:

  GNU nano 2.0.7            File: /etc/resolv.conf

nameserver 10.1.1.1

10.1.1.1 is my routers IP

 

Can you try

Code:

nameserver 145.253.2.75

instead?

 

Ok i have changes it but it still isnt sending mail to the outside of my server in Telaen Webmail.

There may be a possibility that my ISP blocks port 25.

And they have tild me that they do not allow mail relaying due to SPAM.

But they did say i could use their smtp server.

Is there a way i can change my config files to use an external smtp server?

 

ok i just tried to send to my gmail account and it worked!

But when i send to my isp email i get the nasty messgae. I almost looks perosnel

In webmin the mail que status message:

host zuul.ihug.co.nz[203.109.135.49] refused to talk to me: 554-mx.mailfilter1.ihug.co.nz 554 BLOCKED: The SenderBase reputation of your ISP or corporate mail server is extremely bad.

It looks like my isp has blocked my domain

 

I'd talk to your ISP and ask why this happens.
Make sure you have proper SPF and reverse records.

 

ok how would i get SPF records to work to that ISP's will accept my mail that I am sending?

 

You can use the SPF wizard ( http://old.openspf.org/ ) and then copy the SPF line to your zone file.
